mscz-files in Office365 detected as JAR-filetype
As a University of Arts in the Netherlands our docents and students often use musescore.
We use Office365 (Exchange Online) as our E-mail provider with default malware protection.
Unfortunately your mscz-files are detected as JAR-filetype and striped of mails.
I found something of a workaround in one of your fora, but is there a structural solution without weaken our security.
